jQuery ajax returns on all page - php

Question

I want to make something simple but the return of AJAX is coming on all page not to the DIV I want to.
Here is my code PHP: file_ajax.php
<?php
require_once "../../funct/cfg.php";
if(isset($_POST['id'])){
if(fileDB($_POST['id'])){
echo '<script type="text/javascript">
var albhost="albup.ex";
var albbg="111111";
var albvi="2013";
var albid="'.$_POST['id'].'";
var albw=326;
var alblight="D69E9E";
var albfront="C4C4C4";
var albvol=80;
var albas="true";
var albdownb="0";
</script>
<script type="text/javascript" src="http://albup.ex/api/explayer/embed.js">
</script>';
exit;
}
}
?>
and the file ajax: ajax.js
function PrewThis(id,style){
var dataString = 'id=' + id + '&style=' + style;
$("#fileprev").removeClass();
$("#fileprev").show().addClass(style);
$.ajax({
type: "POST",
url: "ajax/file_ajax.php",
data: dataString,
context: "#fileprev",
error: function(){ $("#sidebox").append("SOMETHING ERROR") },
success: function(html){
$("#fileprev").append(html);
}
});
}
And the call is:
<a href="#"
onclick="PrewThis('MRuw2ZbMXj','oranger'); return false"
class="oranger">Sean Paul - Got 2 Luv U (Feat. Alexis Jordan)</a>
Please someone help ?

Answer 1

It's just a guess, but I think this line is the source of your problem...
<script type="text/javascript" src="http://albup.ex/api/explayer/embed.js">
As it states in the jQuery docs: "If html is specified, any embedded JavaScript inside the retrieved data is executed before the HTML is returned as a string."
It seems possible that the included script's output is blowing up your page.
Nothing else in your code seems to indicate a problem. It all looks good otherwise, but then I haven't seen your HTML source.
